A hierarchical lightweight Intrusion detection architecture For sensor networks

Abstract

Intrusions in WSN are mainly based on two types of attacks namely newlineinternal as well as external assaults External assaults are not dangerous newlinebecause the aim of the attacker is to obtain the message not to modify whereas newlinean internal attacker can extend the attack to insert faulty data into the newlinetransmission The assaults from inside are created by compromised sensor newlinenodes which runs malicious code that could steal the key material code as newlinewell as data from correctly functioning nodes and utilize devices for newlineeavesdropping Denial of Service DoS assaults refer to a set of assaults that newlineare sparked by one node or a set of nodes through exploitation of newlinetransmissions for denying other nodes from legal access to resources like newlinebandwidth computational power as well as operating system The common newlinemethod of attack involves ove newline newline
